Add a esp service call that allows a request that supplies a ECL record definition and returns a serialized type info response.
This is similar to
HPCC-18419, which added the option to add the serialized type info to the existing meta data returned by a DFUInfo call. HPCC-18419 is useful for returning a file's meta data together with it's expected on disk serialized type info.
This JIRA will allow arbitrary ECL record translation and will be useful when creating the "output" format in a request to dafilesrv.
